Dear Mentors/Friends, Backpropagation of dz[1] is W[2]T dz[2] * g[1]’ (z[1]) g[1]’(Z[1]) can be any activation function. dz[1] is calculated as dL/dz[1] (Derivative of DL : Loss, w.r.t dz[i]) I am confused with how this equation is obtained: W[2]T dz[2] * g[1]’ (z[1]). There was no explanation…

Thank you for the clarity, that makes sense now!
